  • Raw Mill In Cement Plant Working In Hindi

    Jul 09, 2020 The wet process of cement manufacturing is divided into a number of stages. a) Raw material extraction. b) Grinding. c) Proportioning and mixing and preparing composition based on the raw material purity. e) Preheating the composition. f) Burning the composition in a kiln to form clinkers. g) Clinker cooling with gypsum addition and grounding.(H) CLINKER GRINDING (CEMENT MILLS) Cement grinding mill is similar to that of Raw mill used for raw material finish grinding. There are 3 cement mills A, B and C mill with a clinker grinding capacity of 60 tph for A mill and 50 tph each for B mill and C mill. The B and C mills are identical in construction.Cement production based on the raw material inputs (Vol. III, Chapter 2.2.1.1, Equation 2.3). However, a large number of raw material inputs and the need to continuously monitor their impractical in many cement plants. The different raw materials are normally homogenized before and during the grinding process in the raw mill.Raw materials for the cement production process is decided on the basis of precise examination and analysis data. As a first step, geologists prospect the deposit. 3 From the PC to reality because of the diversity of controls the raw material composition and mill feeding.
